Not everyone will hear them in the same way, it won't be the same experience for everyone, and then there's experimentation/education to really end up at your best curve. The good thing about these IEM's, they're probably low unit to unit variation from what we've seen, so when it comes to IEM's people can experiment with EQ on the basis of these to determine what their ideal IEM target curve would be........for their future reference if EQ'ing other IEM's to their target curve of choice (but it would require some work with REW or Crinacle's graph tool to cement in their preferred target curve for future reference.....not necessary for the majority of folks). I would think for most people that these IEM's would sound absolutely great to fine without EQ.One thing this thread demonstrates beyond any shadow of a doubt: ASR is regrettably just as susceptible to the power of suggestion and and the perils of group think as any other.
I'm listening to Renaissance vocal music right now, which a poster above claimed would be harsh, with or without the magic of equalization. I'm listening without equalization to Josquin des Prez's Missa Pange lingua, on the famous recording as performed by the Tallis Scholars (CD; Gimell, 1986), and it is glorious. It's not remotely anything I'd think could be fairly called "harsh," "shouty," or "shrill." (I think it might do some posters good to listen to an 80s Sony Walkman with stock earphones to help prod their memory as to a sound that actually justifies those epithets.)
Since the Josquin isn't English church music, I moved on to Orlando Gibbons. (No Tomkins in my collection, I'm afraid.) Would my ears be shredded ragged by the harsh, shrill, human voice as reproduced by these dreadfully "shouty," non-EQed IEMs?
Of course not. It sounds just lovely. Orlando Gibbons, "With a Merrie Noyse": Second Service and Consort Anthems, performed by the Choir of Magdalen College, Oxford, with Fretwork, directed by Bill Ives (CD; Harmonia Mundi, 2003.)
In other words, despite how people have been using language in this thread, opinions don't become facts even when repeated over and over again. They're just opinions. And so is mine.
And my opinion is that Amir made a solid recommendation here. I will acknowledge that for some, a little EQ, suit to taste, will make them even better.
